Positivity of Ricci curvature under the Kähler--Ricci flow

Dan Knopf

Published 2005-01-07, updated 2005-01-10Version 2

For all complex dimensions n>=2, we construct complete Kaehler manifolds of bounded curvature and non-negative Ricci curvature whose Kaehler--Ricci evolutions immediately acquire Ricci curvature of mixed sign.

Comments: Added generalization to all complex dimensions n>=2. (9 pages)
